Although Platycraspedum tiheticum was based on 
three syntypes, all of which were allegedly collect- 
ed from eastern Tibet (Xizang), their actual locali- 
ties are in Sichuan, and perhaps for that reason the 
species was not included in the Flora of Xizang 
(Kuan, 1985). However, as cited above, the species 
does occur in Xizang. Of the three syntypes cited

Moraea, with some 195 species (Goldblatt,

of Iridoideae, one of four subfamilies of the Irida-

by l»ifacial, chanru'led to flat leaves and a unique 
type of cormous rootstock consisting of a singlt^ en-

axillary bud. The g<Muis is currently diviih'd into

season, November to Mareh. We have no obser^va- 
tions on the pollination of M. vigil ans but assume 
that, like its relatives M. hrevistyia (Goldblatt) 
Goldblatt and A/, trijida R. C. Foster, it is polli- 
nated by antliophrine bees in searcli of the small 
quantity of nectar held at the base of each outer 
tepal claw (Goldblatt et al., 1989, and unpublished 
data). It is puzzling, however, that while we have 
seen the larg<^ bee, Amegilla capensis, visiting M. 
hrevistyia on three separate occasions and M. trifulu 
once, no visits occuiTed to M. rigihius, although 
that bee was active when the plant was in bloom 
and it was growing within a few meters of the other 
two Moraea species. 

Relationships. Moraea vigilans has the relative- 
ly small flower that lasts at least tw<) days, and re- 
duced, tricuspidate inner tepals characteristic of 
subgenus Meusseuxia of the getuis. Within tlie sec- 
tion it is evidently allied to other Drakensberg sp(^- 

cies of the subgenus, and is perhaj)s most (dosely 
related to the common and widespread Drakens- 
berg species M. hrevistyia (Goldblatt, 1986), with 
which it is easily confused. Herbarium specim<'ns 
of the two species can only be distinguished by 
careful measurement of the floral parts, but wlu-n 
seen alive th(^ difference in tepal ori<Mitation and 
coloring makes it inunediately clear that these are 
separate species (Fig. 2). They actually grow within 
a few meters of one another on tlie slopes of The 
Sentinel: M. hrevistyia grows on deeper soils on 
grassy slopes and M, vigilans is confined to basalt 
outcrops. Their llowcring times overlap, and they 
can readily be compared with one another. It then 
becomes obvious that they are separate sptK'ies. 
The most striking (fifference between the two is diat 
the broadly ovate to orl)icular ou{cr tepal limbs of 
M. vigilans are spreading or held up to 30*^ above 
the plane defined by a right angle relative to the

branches usually exceed the outer tepal limbs by 
up to 3.5 mm, while the white style crests extend 
upward a furtlu'r 5 mm (Fig. 3). Although the two 
species appear virtually identical vegetatively, the 
stalks of M. vigilans are more willowy and tend to 
lean tow^ard the ground, whereas the main stem and 



branches of M. hrevistyia are often stiffly erect. 

Despite its l)eing locally cotniiion and growing 
along a well-used hiking trail, Moraea vigilans ap- 
pears to have been overlooked in the past. As far 
as we have been able to determine, the first collec-

where the vegetation has been burnt or heavily

does not shade out the plants. The species may well 
be more common than is currently believed, but is 

so far known only from Fairfield Estate near Napier. 
Teslaarsdal, some distance west of Fairfield, and 
north of the Potberg, to the east. Plants of the latter 
collci'tion are in fruit, so identification is provision- 
al. Plants from the Teslaarsdal site, collected in 
1976, were assigned to tlu* reflated M. barnardiella 
Goldblatt (as Galaxia harnftrdii G<»ldblatt) by Gold- 

blatt (1979). It seems reasonabh* to assume that M. 
mclanops grows in similar liabitats along die foot of 
the Kl<Mn River Mountain-Rnnlasdori^-Potberg axis. 
Moraea barnardiella is known onl) from Caledon 
and west and north of the town as far as Villiersdorp 

(Goldblatt, 1979, and later herbarium records). 

The purple ll(»wers with a dark center and 
spreading, rather than cupped, tepals recall partic- 
ularly Moraea barnardiella, and it is to that species 
that M. melanops is m<tst closely allied. Vegetative- 
ly, they appear to be identical and only the flowers 
differ. While M. melanops has free, slightl) diverg- 
ing filaments and the style exceeding the anthers 
and with fairly narrow lobes, M. barnardiella (Gold- 
blatt, 1979) has the filaments free in the upper 
third and strongly diverging above, the style divid- 
ing o|)|)osite the middle of the anthers, and the style 
h)lH's theinselves broader than in M, melanops. 

Examination of living plants of this sp(H'i<^s has 

suggested to us an int<Tj>retation of the "inflores-

are subtended by two foliar structures, a shorter 



inner and longtT outer one, both with eloseil 
sheaths and instiled a short distance below the

flower and these two foliar stnictures share a short

Within series Acantholobae, the following new 



is found in the tropics as well as in arid and semi- combinations are proposed: 



arid regions at elevations from sea level up to 2250 
m. Several species grow in temperate areas at 
2000-2750 m (Grether, 1978; Lewis & Elias, 1981; 
Bameby, 1991). 

A taxonomic treatment of the genus for Flora 
Mesoamericana included 47 species wh\\ 28 vari- 
eties (Grether, 1997). In Nicaragua, 19 (40%) of 
these species have been found. Mexico is consid- 
ered the second distributi(mal center of the genus 
after Brazil: 100 to 110 species are known to occur 
in the countr}', and about 60% of them are endemic

3. Series Lactifluae (Barneby) R. Grether 

I propose to treat this group of section Mim^osa 
at the rank of series: 



Mimosa Series Lactifluae (Barneby) R. Grether, 
Stat. nov. Basionym: Series Mimosa, subseries 
Lactifluae Barneby, Mem. New York Bot. Gard. 
65: 571. 1991. TYPE: Mimosa lactiflua Delile 
ex Bentham. 

The groups Xantiae, Psilocarpae, Michelianae, 
and Chaetocarpae (nom. nud.) were included in the 
key for the genus, but not formally named as series 
by Britton and Rose (1928). Barneby (1991) elected 
to recognize none of these. 

The Lactifluae are mainly a Mexican group, ex- 
tending to the province of Guanacaste in Costa 
Rica. The greatest diversity of species is found in 
the Isthmus of Tehuantepec in the state of Oaxaca, 
Mexico, where the following taxa are frequent: Mi- 
mosa deamii B. L. Robinson (endemic to that re- 
gion), M. goldm^anii B. L. Robinson and M. lactiflua 
Delile ex Bentham (states of Puebla, Morelos, 
Guerrero, and Oaxaca), M. melli Britton & Rose 
and M. psilocarpa B. L. Robinson (states of Oaxaca 
and Chiapas), and M. tricephala Chamisso & Schle- 
chtendal (wide distribution from Baja California, 
along the Sierra Madre Occidental (Sinaloa to Chia- 
pas), central Mexico and the state of Veracruz, ex- 
tending to Guatemala, Honduras, and Costa Rica). 
Other species endemic to Mexico are M. sicyocarpa 
B. L. Robinson (Sinaloa to Michoacan) and M. ca- 
erulea Rose (states of Mexico and Morelos). 

In my opinion, the Lactifluae must be treated at 
the rank of series, considering that they form a 
well-delimited group because of their habit, mainly 
shrubby or arboreous, and their morphology, as well 
as by their geographical distribution range. 

Within this series, several new synonyms and two syntypes: Nelson 2775, a flowering specimen 
new combinations, which are part of a Master's the- from Oaxaca, Mexico, and Palmer 88, a fruiting 
sis on the Xantiae group and allied species by Te- specimen from Guerrero, Mexico. However, Bar-

On the basis of examination of type collections lected by Nelson as holotype and the Palmer spec- 
and many other specimens from Mexico, Grether imen as paratype of this taxon. Nelson 2775 is

Guerrero]: Las Higueritas, July 1898, Lang- 
lasse 232 (holotype, G not seen; isotypes, F, 

MEXU, US). 

Mimosa lignosa Micheli had l)een considered a 
synonym of M. nehonii B. L. Robinson (Britton & 
Rose, 1928); however, Barneby (1991) segregated 
it as taxon B in the key to the members of the M. 
xanti complex. Chehaibar and I have examined the 
isotypes, the original description, and illustration of 
M. lignosa, as well as recent flowering and fiiiiting 
collections from the state of Michoacan. Based on 
that material, we agree with Barneby in considering 
this to be a distinct taxon; nevertheless, we place 
it at the infraspecific level. Mimosa tricephala var. 
lignosa is distinguished from M. tricephala var. nel- 
sonii (vide infra) by its completely glabrous leaflets 
with prominent reticulate venation, smaller floral 
bracts and calyx, and by pubescent, not setose, le- 
gumes. It is endemic to the Balsas Basin in the 
state of Michoacdn, Mexico.

section Mimosa by its leaves with 3-6 pairs of pin-

and rachis armed with y<'llow, recurved prickles, 
prickly pevhuudes, and branches pubescent and

pose tlu' rank of series for this group.

quezii is much more distinctively bullate, it has a 
terminal, rather than internodal inflorescence, and 
its flowers are l)orne on pedicels ca. 0.5 mm long, 
rather than the 1.5— 4-mm pedicels of T. restepoae. 
Its long setaceous sepals are also an unusual fea- 
ture in the genus, but most other species with this 
feature share few other characters with T. vasquezii. 
Tournefortia spicata J. S. Miller, another Colombian 
understoiy species with elongate, setaceous sepals, 
differs in its smoother leaf surface, dense inflores- 
cence, and longer corollas.

for ail endemic hnoisicra from Cristalina, CoiAs, in woodland on a slope, campo rupestre, and riverine 

central Brazil. It was first coUeeted by Glaziou in vegetation that is not dense enough to form a gal- 

1895 and th<^n sent to Cogniaux, who named it but lery forest, 
never formally descrilxMl it. Tlie Cogniaux name is 

maintairu'd since it is cit<'d in Glazious published in flower and in fniit, we failed to identify it by 

list of collections and on herbarium specimens. La- comparison with identified specimens o{ Ijjvoisiera

Tlie area around the city of Cristalina, Goids, in 
central Brazil was first botanized by Joseph Em- 

marnicl Pohl in 1818; at that time, it was already 
known as SeiTa dos Cristais (Urban, 1906). Like 
other isolated higldand areas in tlu^ Cerrados do- 
main, it appears to be an important center of en- 
demism. Endemic taxa known to occur In the Scrra 
dos Cristais belong to the l>r(tmeliac<^ae, Rurman- 
niaceac, Compositae, Leguminosae, Malpighiaceae, 
and Myrtaeeae. The region is mined for rock crystal 

and topaz and is a minor tourist center. In ]*>0'l, a 



Tw 

matiM'ial were found, however. This resulted in sur- 
ve)ing taxonomic literature on Linoisiera through 
Judex Keivensis for Windows v. 2.0 (Royal Botanic 
Gardens Kew, 1997), and studying published spe*- 
cies descriptions Un' Liiioisicra (De Caudolle, 1828; 
Triana, 1871; Cogniaux, 1883; Taubert & Ule, 
1896; Iloelme, 1922; Mello-Barreto, 1935, 1936, 
1952: Markgraf, 1910; Wunlack, 1974, 1981, 
1988, 1995). Since we failed to match our spec-i- 
mens with any published description, we tlu^n re- 
quested Elizabeth \^oodgver, a Melastomataceae 
specialist from the Royal Botanic Gard(*ns at Kew, 

to compare our illustration to the Cla/iou speci- 
mens at K collected in Goias. Sht» reported a pos- 
itive match with Glaziou 21312, collected in Cris- 
taUna in 1895, and with a modern sp<'cimen also 
collected in Cristalina {Pirani et id. 1552), and sent 
cybachromc photographs of both specimens to us 
at UB. We later discovered a duj)licale of the (Gla- 
ziou 21312 specimen at the Museu Nacional IbT- 
barium in Rio i!c Janeiro (R). We are confident that 
our specimens are cons{)ecific with the Glaziou and 
Pirani collections, and hereby formally describe the 
species.

Distribution. This species appears to be a nar- giJis Cogn.," and thus Glaziou must have sent the 

row endemic restrii-ted to the Serra dos Cristais, material to Cogniaux for identification. The wood is 

Goias, at 1050-1200 m s.m. Lavoisiera fragilis extremely weak, with even fairly large branches 

grows in sparse cerrado and campo nipestre on breaking quite easily, and this may be the origin of 

shallow, sandy, crystal-bearing soils, frequently the ^])\\\\eX fragilis. The collection locality given by 

forming large populations with Mimosa decorticans Glaziou (1907) is *'Almocafre, Serra dos Crystaes,

Paris, Kew, and Berlin, but we have accessed only couraging comments on the paper, 
two collections, one in Kew and one in Rio de Ja- 



neiro. 



Since this name is cited in Index KeivensLs and 
published in the Glaziou collections list (Glaziou, 
1907), we feel it has entered the literature and have 
chosen to maintain it.

The Sesse and Mocino expedition to New Spain 

(1787-1803) recorded many interesting obsena- 

tions, especially regarding the flora of Mexico. For 
a description of the expedition and its aims, travels, 
collections, paintings, and in particular its botani- 
cal accomplishments, see articles by McVaugh 
(1977, 1980, 1987, 1990, 1998) and a recent sum- 
!naiy and update by Bartholomew and McVaugh 
(1997). Plant collections from the expedition are 
housed at a number of European lierbaria as doc- 
umentation for various early reports and names, but 



in 1819 (see nomenclature below).

Epithet, This plant is named in honor of Joao 

Semir (State University of Campinas, Brazil), who 
has gn'ally contributed to our knowledge of the 

Brazilian flora. 

Distribution unci habit at. Thelypteris semirii is 
entlemie to the '^Zona da Mata" n^gion in the State 
of Minas Gerais, Brazil, and grows in shaded areas 

in the primary an<l secondary Atlantic Rain Forest, 
from 300 to 700 m. This new species is coimnon 
only in the Rio Duee Slate Park, betVNt'rn 19°41'— 

lO^-iO'S and 12^38 '5"-18°28'W and is rare outsido 

this n^gion. 

The new species belongs to Thelypteris subg. 

Conioptcris, due to the indum(*nt of trichomes fur- 
cate and stellate on scales, [)etioles, rachises, and 
costa. It is very similar to T. scabni (from Argentina, 
Paraguay, and southeastern Brazil) in pinna shape, 
indumetil disposition, prominent siiuis<'s, and un- 
branched trichomes on sporangial stalks. However,

truncatum S. Q. Tong (1987), not Stokes (1812). mum gagnepainii differs from A. yunnanense in 

Therefore, the following new names (nomina nova) having flowers yellow (vs. white), with calyx to only 

are proposed here, respectively: A. gagnepainii T. 1 cm (vs. 1.5—2 cm), labellum spatulate-flabcllate

Forty years later, Kitagawa (1979) proposed a new 

combination, Dimorphostcmon pinnatus (Pcrsoon) 

Kilagawa, based on the second earliest available 
epithet, //. pinmitd^ and did not list Cheiranthus 
pinnatijidus in the synonymy. Earlier, Golubkova 
(197'ia, b) proposed th<^ combination Dimorphoste- 

mon pectinatus (DC.) Golubkova, thus adopting the 

fifth oldest epithet for the species. Strangely, Go- 
lubkova (1976) maintained D. pectinatus and fol- 
lowed de Candolle (1824) and Kitagawa (1939) in 
reducing ih*^ earlier published epithets to synony- 
my. Willdcnow's epithet {pinnatifidus) clearly is the 
earbest (1800) available name for the species, and 
a new combination is herein proposed. 

Dvofak (1972) proposed the new genus Alaida, 
but this name is illegitimate because it included .4. 
pectlnata (DC.) DvoMk, which is a synonym of tlie 
type oi Dimorphostemon, Dimorphostcmon aspcr (= 
DofUostenion pinnatijidus). A key for the determi- 
nation of the 10 species of Dontostemon is pre- 
sented.

Abstract. The taxonomic limits of 5ym/emoa are has glabrous filaments and petal claws, 2-lobed 

established, and its relationship to Dontostemon is stigmas, nonmucilaginous seeds, median filanK^nts 

discussed. Synstemon lulianlianus, a new species united near to the apex, flattened replum, no me- 

from Gansu, is described and illustrated. Previously dian nectaries, straight or slightly twisted terete tri- 

described taxa in Synstemon are reduced to syn- chomes, and (in four species) well-developed mul- 



onymy ol S. petrovii. 



The genus Synstemon was established by Bot- 



ticellular glands. The two genera share many 
characters, and it appears that Synstemon is more 
closely related to Dontostemon than to any other

Although we have not examined the type of 5}7i- 
$t€nu*n deserticola, the detailed description and il- 
lustration leave no doubt that it is a synonym of S. 

petroiii. The trichome density on leaves, stems, and 
sepals of 5. petrovii exhibits continuous variation 

and, therefore, variety pilosus (with densely pubes- 
cent sepals) and varit^ty xinglon gnicus (with gla- 
brous leaves and stems) do not merit recognition. 
The type of S. petrovii has glabrous sepals, but the 
additional coUection cited above has sparsely pu- 
bescent sepals and leaves. Synstemon petrovii also 
varies in the density of trichomes on the filaments.

Ams in AC'i'. Chorispora tashkorganica, a narrow 
endemic to western Xinjiang, China, is described 
and illustrated. Its relationships and distinguishing 
characters are discussed. 



During work on the genus Chorispora R. Brown 



for the forthcoming vol 



eight of the Flora of 



China, we examined all of the recognized species 
except the two described by Pachomova (1974) 
from central Asia. However, on the basis of the de- 
tailed original descriptions she gave, it appears that 



Chorispora pamirica Pachomova and C. insignis 
Pachomova are synonyms of C songarica Schrt^nk 
and C sihirica (L.) DC, respectively. Among the 



extensive Chi 



material we examined, two col- 
lections clearly belong to an undescribed species. 



hereafter known as C tashkorganica. Regardless of 
the ultimate placement of Pachomova's two taxa, 

re quile different fnmi the new species in

having obovate petals 10-12 mm long, compared 

to the nmch shorter (3-^ mm hmg) oblanceolate 
petals of C. tashkorganica. 

As presently delimited, Chorispora consists of 11 
species centered primarily in central and south- 
western Asia, with the range of one weedy species. 



C tcnella (Pallas) DC, extending throughout Eu- 
rope and introduced elsewhere in the world. The 
11 species of Chorispora are easily separated by 
the following key.

Maianthemum F. H. Wiggers for the Flora of Chi- to 3500 m in southern Gansu, Sichuan, northwest- 

na, volume 24, it was found that two taxa formerly em Yunnan, and possibly Shaanxi provinces, and 

treated under Smilacina Desfontaines required the M. tubiferum occurs from 2500 to 3000 m in Gansu, 

following new combinations in Maianthemum, Hubei, Qinghai, Shaanxi, and Sic-huan provinces; 

namely M. fusciduliflorum (Kawano) S. C. Chen & both are endemic to China. 
Kawano and M. stenolobum (Franchet) S. C. Chen 
& Kawano. 



The genus Maianthemum (including Smilacina) 
consists of about 35 species and is widely distrib- 
uted in the northern temperate zone as well as 



subtropical montane Asia and Central America. 
Two genera, Smilacina and Maianthemum, have 
been recognized traditionally and historically. 
LaFrankie (1986) concluded that the difference 
between them (trimerous vs. dimerous flowers) was 
not sufficient to warrant distinct genera, and there- 
fore transferred the species of Smilacina to 
Maianthemum. Along with Li (1990) and Hara 
(1987), the present authors agree with LaFrankie's 
transfers and note that the following combinations 
are necessary for their forthcoming treatment of 
Maianthemum in the Flora of China, volume 24 
(Chen & Kawano, in press).

ragua, and Costa Rica to the Darien of eastern Pan- 
ama. Future collecting may reveal its presence in 

both Belize and the Choco of Colombia. It occurs 
from sea level to 1650 m in altitude. In contrast, 
Dichorisandra hexandra has a continuous distri- 
bution from Peru and French Guiana to Panama 

and Costa Rica, and is disjunct in Belize. Although 

D. amabilis and D. hexandra are known from both 
Pacific and Atlantic slopes, D. amabilis tends to 

occur (or is at least collected more frequently) on 

Pacific slopes, and D. hexandra more so on Atlantic 

slopes (at least in Mesoamerica). Furthermore, D. 

amabilis is most commonly found in sunny, dis- 
turbed sites often near streams or on alluvial ter- 
races, whereas D. hexandra is restricted to shady 
primary forest.

dor and Colombia (primarily in the Choco phyto- 
geographical region) in primary forests from sea 
level to 1150 m. In Colombia, it has also been col- 
lected in Cauca and Valle, but not yet in Narino 
where it probably occurs as well. Several sterile 
specimens from the department of Choco are sus- 
pected to represent S. gentryana, but cannot be dis- 
tinguished with confidence from S. cristata (see dis- 
cussion below). Flowering and/or fruiting material 
has been collected in every month of the year. 

Etymology. The species is named for the late 
Al Gentry who, during inventory work in the Choc6 
region, collected it at least nine times. 

Common name. Comida de mono (Ecuador; in- 
dicating possible seed dispersal by primates). 

Siparuna gentryana resembles 5. cristata (Poep- 
pig & Endlicher) A. DC. in leaf shape and vena- 
tion, but that species has smooth fruits that reach 
3.5-4 cm in length, whereas S. gentryana fruits are 
tuberculate or spiny and only half that size. In S. 
cristata^ pedicels of the male flowers often elongate 
luring flowering, becoming up to 2 cm long, a char- 
acter not seen in 5. gentryana^ where pedicels re-

Etymology. The species is named to honor its 

collector, RodoUo Vasquez, curator of Peruvian ma- 
terial at the Missouri Botanical Garden and author 
of the first comprehensive florula for the Peruvian 
Amazonian lowlands (Vasquez Martinez, 1997).

Because of the hairy leaf sheaths and the broad 
outer phyllaries, Oritrophium Uanganatense would 
key to 0. limnophilum in Cuatrecasas (1997), the 
only other species in the genus with such involucral 
bracts. From this species, 0. Uanganatense differs 
by the bright yellowish green color of the upper 
surface, the densely lanate lower surface, and the 
revolute margins of the leaves. The name of 0. llan- 
ganaterise is derived from the name of the Llan- 
ganatis National Park, where the species was col- 
lected.

forests in Brunei and probably also Sabah, is de- petiole 1.5^.5(-8) X 1.5-2 mm; lamina subovate-

and sharply acuminate leaf blades, cauliflorous and and sharply acuminate, acumen to 4.5 cm long, 
ramiflorous inflorescences, stamens lacking ventral base rounded to subcordate, ± asymmetrical, mar- 
appendages, and gynoecium with densely short-pu- gin serrulate, 5 to 9 serrations/5 cm, texture char-

According to Huang and Li (1990) and Huang Campylandra emeiensis (Z. Y. Zhu) M. N. Tamura, 



and Hong (1997), Campylandra has unimodal kar- 
yotypes, and ellipsoid or subspherical, monosulcate 
pollen grains with reticulate or perforate exine, 
whereas Tupistra has bimodal karyotypes (except in 
T nutans Wallich ex Lindley: unimodal), and 
spherical, inaperturate pollen grains with rugulose, 
verrucose, or gemmate exine. Thus the separation Campylandra ensifolia (F. T Wang & Tang) M.

of Campylandra and Tupistra is more or less sup- 
ported by karyological and pollen morphological 
data, although comprehensive karyological and pol- 
len morphological studies are needed to confirm 
this. The separation of the two genera has also been 
supported by molecular phylogenies based on both 
frnK (including maiK) and rbch genes (Yamashita 
& Tamura, in press). At the present stage, we con- 
sider that separation is better than inclusion of 
Campylandra within Tupistra. However, the de-

the identities of previously described species. As what lanceolate, 3-7 mm long, acute to acuminate 
circumscribed by Taylor (1997), Palicourea is dis- or bidentate. Inflorescences terminal, erect, with pe- 
tinguished within the Rubiaceae by its persistent duncles 3.5-11.5 cm long; panicles shortly pyra- 
stipules that are united around the stems into a midal to somewhat corymbiform, 2.5-8.5 X 3-6 cm 
continuous sheath and bilobed in the interpetiolar excluding corollas, with 4 to 6 pairs of developed 
portion; generally colored inflorescences with the secondary axes, these often subopposite to alter- 
flowers usually pedicellate; corollas that are usually nate, with flowers pedicellate in cymules of 3 to 7; 
brighdy colored, usually five-lobed, and have well- bracts entire to ciliolate, those subtending second- 
developed tubes that are somewhat swollen at the ^ry axes triangular, 0.5^ mm long, acute, those

ing; and drupaceous fruits with usually two py- ^uncle, axes, bracts, and pedicels puberulous to 
renes. This Neotropical genus includes about 200 glabrescent, leA; flowers distylous, with hypanthium 
species found from sea level to high montane re- cylindrical to turbinate, ca. 1 mm long, glabrous to 
gions. The species are^ typically distylous and ap- puberulous; calyx limb puberulous to usually gla- 
brous, divided nearly to base, lobes ovate to deltoid 
or shortly trilobed, 0.8-1.1 mm long, acute to cus- 



parently pollinated by hummingbirds.

the largest genus in the Periplocoideae and consists 
of geophytic herbs with a few climbers that inhabit

As no fresh, or spirit, material was available, one 
flower from each of the two Merello et al. 962 (K, 
MO) specimens was rehydrated and examined. For 
light microscopy (LM), pollen from these flowers 
was acetolyzed according to Erdtmans (1960) 
method, mounted in glycerine jelly, and sealed with 
paraffin wax. Samples were examined using a Zeiss 
photomicroscope. All measurements were made

Distribution and ecology. Raphionacme sylvi- 
cola was found climbing in forest vegetation around 
a steep, rocky waterfall at an altitude of ca. 915 m. 
The Nsumbu (or Sumbu) National Park falls within 
the Itigi deciduous thicket, which is a smaller unit 
of the wetter Zambezian miombo woodland (White, 
1983). The collectors regarded /?. sylvicola, which 
was collected in December, as "uncommon." 



Discussion 

Raphionacme sylvicola is similar to R. montei- 



lobes; anthers basally fused with stigmatic head, roae and /?. flanaganii in the climbing habit, and 
free from one another, ovate with apiculate apices to a certain extent in floral structure. However, the

Allium atrosanguineum is a Central Asian and 

Chinese species sometimes treated as A. monadel- 

phum, e.g., by Vvedensky (1935: 146-147). It is 

characterized as follows: roots thin; bulbs cylindric; 

leaves terete, fistulose; scape terete; filaments 

shorter than tepals, connate into a tube for 1/3-3/4 

their length, entire; ovary with ovules 2 to several

Distribution and ecology. This speries occurs 
in department olTarija, Bolivia, and in the provi 
of Jujuy, northwestern Argentina, between 1000 
and 2300 m elevation, on humid grasslands and the 
margins of rivers. According to Cabrera (1976), 
Paspalum rolcanensis has been reported from tlie 
Yungas province and transitional areas between the 
Yungas and the Pn^punena provinces, in immature, 
permeable, rocky and sandy soils. 

Chromosome number: n = 20 (Hunziker et al., 
1998, under Paspalum aff. malacophyllum).

SubgtMUis Anachyris (Nees) Chase of Paspalum 
can be distin*i;uished by its concavo-convex spike- 
lets, the upper lemma having conspicuous nerves 
on the abaxial surface (Fig. 1). The new species 
agrees with these characters and dierefore is in- 
cluded within this subgenus. Within subgenus .4n- 
achyris, P, volcanensis is related to P, usterii, the 
only other species of this subgenus with pilose 
spikelets with a developed upper glume, which is 
absent in the remaining species of the subgenus. 
Paspalum usterii differs by its long and robust rhi- 
zomes, inllorescences 12-35 cm long with 12—60 

branches, and spikelets 1 .8-2.4 mm long, 

with the upper glume l-B-nei-ved, reaching Vi to % 
the length of the spikclct and the nerves not man- 
ifest; this species grows in southern Brazil, eastern 
Paraguay, and Argentina, in the province of Mi- 
siones.

Tlie genus Aq)ophyllum is a small group of very 
similar species, with little variation in flower structure. 
CorreU (1947) recognized only two species, A. alpin- 
um and A. spicatum La Uave & Lexarza, differing in 
the length of the sepals, petals, and lip. Arpophyllum 
spicatum^ the type of the genus, is quite distinctive in 
its thick, succulent leaves. As noted by Garay (1970, 
1974), A. luxiflvrum is also clearly distinct in its sub- 
entire lip and the puberulent surface of the ovaries. 
Garay recognized five species, with A. medium being

Dressier, A. giganteum subsp. medium (Reichen- 
bach f.) Dressier, and Scaphyglottis pachybulbon

This paper continues the descriptions of new 
species found in the preparation of the Orchidaceae 
for Flora Mesoamericana and new combinations 
needed for that treatment (Dressier, 1997, 1998). 



While the aspects of typical A. alpinum^ A, gigan- 
teum, and A. medium are distinctive, tliere is much 
variation, with the limits between A. medium and the 
other two being unclear, though A. alpinum, of high 
elevations, cannot be confused with A. giganteum, of 
low elevations. As A. medium is intennediate between 
these and I find no feature that will consistently dis- 
tinguish it from either extreme, I am compelled to 
treat all three as subspecies of A. giganteum.

several varieties, depending on the presence of 5 
large and 2 smaller keels in C. aiirea, or, In C 
laevis, 3 large and 2 smaller keels. This system 

(Allen, 1955) ignores significant differences in the 
keels and in other features, but was used for many 
years, partly because so little material of the genus 
is available. The two new species described here 
are both allies of C laevis, having thick pseudo- 
bulbs and smooth keels on the lip. Another plant, 
more similar to C. aurea and painted by Rodriguez 
C, is also clearly undescribed, but I have seen no 
pressed material of the species (Rodrfgucz C. et ah, 
1986). There are plants, apparently of this species. 



This species resembles C. laevis in having three 
large keels on the lip, but the keels are laminar, 
rather than thick and fleshy. The flower parts are 
all shorter and proportionately wider than in C lae- 



vis. The most distinctive feat 



ofth 



e species are 



found on the column foot. The foot has small, 
rounded wings beyond the middle, and distal to the 



wings there is a curious appendix between the col- 
umn foot and the lip. The epithet, addita, refers to 
this appendix or addition. This very distinctive spe- 
cies is known only from the type but should appear 
elsewhere in Chiapas and in Guatemala. 



in cultivation, and I believe its description should 
wait until specimens are available.

Chysis orirhalcea also resembles C. laevis but 
differs in having shorter and wider perianth seg- 
ments and in the strongly convex lateral margins of 
the lip (when flattened). Like C addita, this species 
has something of a callus at the tip of the column 
foot; a similar, though smaller, callus may some- 
times be found in C. laevis. The epithet orichalcea 
is derived from the Latin orichalcum, chalcopyrite 
or foolV gold. Though the flowers of this species are 
quite golden, it is not the real C. aurea, whose 
thick, puberulent, subequal keels diverge distally.

The taxonomy of Scaphyglottis is in relatively 
good order because of Adams s (1993) recent re- 
vision, but several novelties have appeared since 
the 



revision.

unlike that of S. bicallosa.

northern Peru is mainly recognized by its tomentose but sometimes in fascicles of 2 to 8 flowers (Burger

Abstract. While preparing a monographic study Eleutherococcus brachypus (Harms) Nakai var. 

of Eleutherococcus^ we discovered the three new 



taxa, E. brachypus var. omeierisis, E. huangshanen- 
sis, and E. pseudosetulosus, described here. In ad-

chiisanensis, E. pilosulus, and E. pubescens, are pro- 
posed. 



Eleutherococcus Maximowicz (1859, emend. C. 
H. Kim & B.-Y. Sun) is an endemic Asian genus 
with about 35 species distributed mainly in north- 
eastern Asia including China, Korea, and Japan, 
with some members also extending to southwestern 
Asia (Kim, 1997). The genus Acanthopanax (De- 
caisne & Planchon) Witte was initially recognized 
as a subgenus of Panax L. by Decalsne and Plan- 
chon (1854) and raised to generic rank by Wille

Distribution and habitat. Secamone schatzii is 
only known from the type collection from Nosy 
Mangabe in the Bay of Antongila on the east coast 
of Madagascar. It was climbing to 16 m above 
ground into the canopy. It was collected in flower 
in January. 

Secamone schatzii is known from low altitudes in 
the eastern rainforest zone, in contrast to 5. gla- 



axillary (sometimes appearing terminal), much 
shorter than the adjacent leaves; cymes di- to 
monochasial, rather dense with up to ca. 8 flowers; 
axes up to 5 mm long, covered with few reddish 
hairs, often more densely hairy along one or two 
sides; pedicels up to 1.5 mm long, usually hairy;

carpels, subiriferior. Style absent. Style head pro- 
jecting above the staminal column; narrower upper 
part slightly shorter than the lower broader part, ca. 
0.5 mm long, cylindric, entire at the apex. Follic-le 
(only gall-infested one seen) ca. 2.0 X 0.8 cm, nar- 
rowly ovoid, straight, glabrous. Seeds not seen. 



Distribution and habitat, Secamone linearis is 
only known from the type collection from the Ma- 
rojejy mountains at 1300-1500 m altitude. Habitat 
unknown. It was collected in flower in January. 

Secamone linearis from the Marojejy mountains 
in the northeastern part of Madagascar most resem- 
bles S. sparsiflora from the Isalo mountains to the 
southeast. Both species probably represent isolated 
segregates of the rather common Secamone tenui- 
folia, whose wide distribution lies between 5. li- 
nearis and S. sparsiflora. There is, however, a dis- 
junction between Secamone tenuifolia and 5. 
linearis^ as 5. tenuifolia has not been found north 
of the Antananarivo area (Klackenberg, 1992: 85), 
some 500 km south of the Marojejy mountains. 
Both Secamone linearis and S. sparsiflora lack the 
distinctly tuberculate-papillate lower leaf epider- 
mis, but both share with 5. tenuifolia narrow, usu- 
ally linear leaves. Secamone linearis differs from S, 
sparsiflora by its shorter and hairy pedicels (1—1.5 
mm vs. 3.5 mm long and glabrous), its reddish 



hairy inflorescence 



(vs. glabrous), a twining 



habit (vs. a shrubby one with erect or spreading 
branches), as well as by its dorsiventrally flattened 
and truncate staminal corona lobes (vs. acute to 
obtuse lobes, dorsally rounded, as seen in S, spar- 
siflora and 5. tenuifolia). It has tuberculate-papil- 
late inner surfaces of the corolla lobes, like Seca- 
mone glaberrima, S, sparsiflora, and S. tenuifolia, 
but differs from them in that the corolla lobes are 
not distinctly valvate. In this character it is instead 
more similar to Secamone schatzii in that the lobes 
become thinner toward the margins and are slightly 
overlapping each other with their left margins as 

seen from outside. 

The epithet of this species alludes to the narrow 
1 



eaves.

tute the Secamone tenuifolia group discussed in the 
text is presented below, also serving as a character

It is most similar to the type species for the genus {2n = 30) characteristic of cultivated relicts of ex-

states of Rio de Janeiro and Sao Paulo in south- tive to the various forest ecotypes of the Mata At- 

eastern Brazil. It differs from this species by its lantica and the nearby northeastern regions of the 



cuneate leaf bases, and more numerous, entirely Caatinga Province (Oliveira-Filho & Ratter, 1995).

The etymology of Adenocalymma Martius ex Adenocalyimna magnoalatum Scudeller, sp. nov. 



Meisner is complex. The name is a compound of 
adenos (aSeuo^ f. = glands) and calymma {KaAvix- 
jia n. = head-covering); these characteristics are 
found in almost all species of the genus. Meisner 
(1840) published the original description of the ge-

This species of Matelea subg. Matelea is close faucal annulus, cream to yellow, abaxially ap- 

to M. dwyeri Morillo, which was treated as M. me- pressed-pubendent, adaxially hispidulose, hairs 

diocris Woodson in the Flora of Panama (Spellman, translucent, unicellular, erect, ca. 0.05 mm long, 

1975). Matelea dwyeri is endemic to the area of tube 0.4—0.6 mm long, lobes lanceolate, 2.3-3 X 

Cerro Jefe, Panama, at about 800-1000 m eleva- 1.3-1.9 mm, apex rounded, annulus erect, 0.3-0.5 

lion, while this new species is found at low eleva- liim long, distally with 10 inconspicuous, rounded 

tions along the Caribbean coast of Nicaragua. Ma~ lobes; corona ± horizontal on stipe of gynostegium 

telea dwyeri has stems with two rows of hairs (a between annulus and gynostegium, glabrous, 10- 

mixture of long, reflexed hairs and short glandular lol)ed with each lobe bifid at tip, 0.4-0.6 mm wide, 

hairs), coriaceous leaves with 4 to 7 pairs of veins, lobes alternate with anthers deflexed and lobes op- 

and calyx lobes tinted puqile. Matelea elarhyantha posite anthers turned upward, anthers ellipsoid, 

has glabrescent stems with a few^ long, reflexed 0.4^0.5 X 0.7—0.8 mm, terminal appendages ap- 

hairs at the nodes, membranous leaves with 7 to 10 pressed to margin of style apex, 0.1-0.15 X 0.6- 

pairs of veins, and green calyx lobes. Both species 0.8 mm; corpusculum 0.15-0.16 X 0.07-0.09 mm, 

share the unusual character of an apiculum at the sagittate, pale brown, translators 0.07-0.08 X

Medium-sized trees, to 17 m. Twigs terete, solid, 
species are here described. A number of the new densely golden brown pubescent when young, the 
species had earlier been recognized as undescri- hairs erect, somewhat eurled, completely covering 
l)etl, but a description was postponed until more the surface, the indument wearing off on older 
complete material was available. Some of the new twigs; terminal buds densely pul>escent with as- 
species, such as Ocotea cinerea and O. nigrescens, cending hairs, the surface completely covered. 



Manaus, Briizil, a ruunber of Lauraceae were found 
that couhl not be identified. The proximity of the 
Reserva Ducke to Manaus made it possible to col- 
lect flowers and fruits from the same tagged trees 
and to search for, and find, staminate and pistillate 
trees of most dioecious species. Several of these

The fact that intensive collecting in a relatively ceous when young, the surface completely covered

Habitat. Terra firme forest on clay soil. 

Ocotea delicata is a small tree that can be easily 
recognized by its tripliveined leaves, slightly im- 
pressed major veins, and the densely tomentellous 
twigs and inflorescences. It shares with Ocotea laxa 
(Nees) Mez and Ocotea tarapotana (Meisner) Mez, 

both members of the Ocotea cernua group (sensu 



Rohwer, 1986), tripliveined leaves with slightly im- 
pressed major veins. However, these two species 
have glabrous or sparsely appressed pubescent 
twigs (the indument not obscuring the surface as in 
0. delicata)^ glabrous or almost glabrous flowers 
and inflorescence branches, and domatia in the ax- 
ils of the lowermost lateral veins. These vegetative 
characters alone allow an easy distinction of these 
species. In addition, in staminate flowers of 0. laxa 
and 0. tarapotana the pistillode is reduced to ab- 
sent or at least without a conspicuous stigma, and 
the glands of inner stamens are globose, not flat- 
tened as in 0. delicata. The fruits and cupules of 
Ocotea tarapotana are not yet known; 0. laxa has 
a fruit and cupule (with persistent tepals) similar 
to those of 0. delicata, Ocotea delicata is only 
known from the vicinity of Manaus and toward the 
east until the Rio Trombetas, on the north side of 
the Amazon Casin.

Ocotea scabrella resembles 0. bofo and 0. rub- 
rinervis in having cupules with persistent tepals, 
but differs in the absence of domatia, in the very 
short, erect indument of the twigs, in the spreading 

tepals at anthesis, in the clustered flowers, and in 

the very small pistillode without a stigma in the 
stamijiate flowers. The pubescent receptacle of the 
staminate flowers is also a useful character. Ocotea 
amazonica differs from 0. scabrella in the longer,

The relatively large cupulas, the ovoid fruits, the 
frequently terminal-appearing inflorescences, and the 
small domatia, which sometimes may be lacking, sug- 
gest a relationship of 0. subterminalis with 0. schom- 
burghiana. The latter species differs in having smaller 
cupulas and fruits, smaller leaves and inflorescences, 
and in the lack of the very short, erect indument on 
the twigs. Various labels mention that the slash is 
orange and the wood fragrant.

Wt'rff & Rirhter, 1996). The 2-(:elle(l outer 6 sta- 
mens point to Endlicheria, while the 4-cene(I inner 
3 stamens indicate Rho do ste mono daphne. Indeed, 
both E. anomala (Nees) M<*z and R. revolutijolia 
Madrinan have six 2-relled and three 4-celled sta- 
mens. However, broad, sessde stamens occur fre- 
quently in Rhodostemonodiiphne and not or rarely 
in Endlicheria; broad, sessile stamens are fountl in 
E. ruhrijlora Mez, a species only placed in Endli- 
cheria because oi its 2-eelled stamens. The indu- 
ment ol twigs and leaves and the leaf venation of 
R. recurva resemble species of Rhudostemonoda- 
phne such as /?. grandis (Mez) Rohwer and relat*^! 
species and R. capixabcnsis Baitcllo & Coe Teix- 
eira. This similarity led me to place the new spet:ies 
in Rhodostemonodaphne. Possibly the closest rela- 
tionship is with R. revolutijolia Madrinan, which 
has the same stamen configuration, but which dif- 
fers in having erect hairs on the lower leaf surface 
and larger leaves. Vegetatively, R. recurva is quite 
similar to R. peneia Madrinan, and both species 
occur near Manaus. They can be separated as fol- 
lows: R. recurt'a has recurved leaf margins, densely 
pubescent twigs (with the surface completely cov- 
ered by the indument), and 3 or 4 lateral veins, 
wliile R. peneia has flat leaf margins, spars(dy pu- 
bescent twigs with the surface largely visible, and for lliis species could he entered in TahK: 1. W liclher (),

This species is variable in habit, foliar size, and include its pronounced foliar dimorphism at each

dividuals are free-standing trees. In others, all bracts, and laterally connate anthers with connec- 

plants encountered are epiphytic shrubs. In foliar tives that are keeled dorsally and modified dorso- 

size, some individuals have uniformly small leaves basally into a deflexed spurlike appendage.
